Yesterday director Zack Snyder tweeted the above teaser picture of the next Batmobile, and later revealed a more complete look of Bat’s new ride from what looks like a movie still. Far from the military-styling of Christian Bale’s Batmobile, Affleck’s ride look lower, sleeker, and more, dare I say, comic book-y? Looks aside, more interesting is word that the functional movie prop might shun the traditional V8 engine of Batmobiles past in favor of a gas-electric hybrid setup, according to Jalopnik’s unnamed sources.

A functional Batmobile is necessary for filming, and Batmobiles of the past often went with the tried-and-true small-block Chevy V8, even though some of them were supposedly turbine-powered. A few private a Batmobile concepts have gone even further, embracing clean-burning hydrogen fuel cells.

If there’s some reason that a hybrid would make sense on the movie set, then that makes sense. A zero-emission electric vehicle, for example, would be ideal for shooting scenes in an enclosed space. But if it’s just a nod to Affleck’s environmentalism, then what a waste of money for absolutely no environmental benefit.
